VALVE-GEAR.

To all whom it may concern Be it known that I, JACOB J. MoocK, a citizen of the United States, residing at Orrville, in the county of Wayne and State of Ohio, have invented a new and useful Valve-Gear, of which the following is a specification.

The present invention relates to improvements in valve gears for hydraulic pumps, one object of the present invention, bemg the provision of a simple form of valve actuating mechanism controllable from the connecting rod between the engine piston and the pump piston, so that the valve for admitting the pressure fluid to operate the engine will be controlled automatically with the fewest number of parts and operations.

A further object of the present invention is the provision of a novel form of valve gear, in which an oscillatory lever actuated by the connection between the engine and pump piston, operates a V-shaped head connected to-and carried upon the free end of the valve stem, in conjunction with a stationary inverted V-shaped member, whereby the first mentioned V-shaped member is engaged and guided by the last V-shaped member during the oscillation of the lever to impart the desired oscillatory movement to the steam admitting valve.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a side elevation of a hydraulic pump, the connecting frame between the cylinder of the pump and engine being broken away to show the connection of the present invention therewith. Fig. 2 is a section taken on line 22 of Fig. 1.

Referring to the drawings, E designates the engine, V the valve chest therefor and P the pump, the connecting frame 1 being disposed between the two as is usual, while the pistons (not shown) of the respective engine and pump are connected by the rod R.

A pin 2 is connected to the rod and adapted to enter the slot 3 of the lever 4, said Specification of Letters Patent.

Application filed June a, 1914. Serial No. 843,798.

lever 4 being pivoted upon the pin 5 for swinging movement, and such pin being carried by the upright plate 6 formed integral with the connecting frame 1. Fixed upon the pin 5 and also constituting a means to hold the lever 4 in place, is an inverted ti-shaped block 7, while carried by the lever 4; are the two diverging arms 8 and 9.

Upstanding from the plate 6 is a plate 10, which is provided with the apertured lug 11 for the slidable reception of the rod 12, the rod 12 having disposed thereupon, a coiled spring 13 which bears downwardly to hold the free end of the plate or valve actuating member 14 of the valve actuating plate 15 downwardly, so that the open V- shaped frame or end 16 thereof will be held always in contact with the inverted V- shaped block 7.

As illustrated inFig. 1, the arms 8 and 9 are disposed to fit astride the member 16, so that as the lever l is oscillated, either one of the arms 8 and 9 will engage the member 16 and thus impart the desired reciprocatory movement to the valve actuating stem 15. As the spring 13 holds the end ll and consequently the member 16 resiliently down upon the block 7, such end will ride upwardly or downwardly upon the block according to the location of the lever 4: and thus imparts the desired rapid movement at the end of each stroke of the stem 15 and a gradual movement to the same during the period that the member 16 is riding upward upon either inclined surface of the block 7.

Any form of valve may be used in the chest, the present mechanism for controlling the same being the essential features.

What is claimed is:

The combination with a cylinder, a valve shaft and a piston rod, of a valve actuating mechanism, including an oscillatory lever having a slot in one end, a pin connected to the piston rod and fitting in said slot, whereby the reciprocation of the piston rod oscillates the lever, a V-shaped block carried by the lever and inverted, a supporting plate, a pivoting pin connecting the lever to the supporting plate, an arm attached to the supporting plate and projecting thereabove, a 'alve stem having an open V-shaped frame in one end with the apex thereof normally in contact with the V-shaped member of the lever, a spring connected to the free end of the valve stem and bearing against the upper end of the arm carried by the plate for the valve stem for engaging the sameas the leverls oscillated.

holding the V-shaped end thereof in con-V Intestimony thatIclaim' the foregoing as tact With the V-shaped member of the lever, and two divergent arms'having extensions carried by the lever adjacent the pivotal end thereof, said terminals thereof being disposed to fit astride of the'V-shaped endof in "the presence of two witnesses.
